Impeller Types and Purposes

Three Main Types of Impellers We offer three different types of impellers for many of our molten metal pumps. (The impeller is the vaned wheel that spins inside the pump base.) The impeller and its interaction with the pump base (and base volute) largely determine the performance characteristics of a given pump design. Each impeller ...
